  When the power switch 305 is turned on, the one-chip microcomputer 102 of the control circuit 100 first performs initialization S1, as shown in FIG. 6, and thereafter repeatedly executes process 1, process 2 and process 3 in order.

  The contents of process 1, process 2 and process 3 are all the same as shown in FIG. For this reason, only the content of the process 1 is demonstrated below.

  In FIG. 7, it is first determined whether or not energization is performed on the heat-shrinkable metal wire 40 (S11).

  Immediately after the power switch 305 is turned on, the power is not yet energized, so the determination result in S11 is “NO”, and then it is determined whether the waiting time is being measured (S12). Here, as will be described later, the waiting time is a time when measurement starts at the time when the energization of the heat-shrinkable metal wire 40 is started (third time point t3), and the leaf portion 30 of the carnivorous plant model 2. Is a fourth predetermined time (in this embodiment, for example, set to 12 seconds) corresponding to the time required from the closed state to start to fully open.

  At this time, the determination result in S12 is “NO”, and then it is determined whether or not the sensor 1 is switched from OFF to ON (S13).

  At this time, the determination result in S13 is “NO”, and then it is determined whether or not the sensor 1 is in an ON state (S14).

  At this time, the determination result in S14 is “NO”, and the process 1 is exited.

  Thereafter, in process 1, S11, S12, S13, and S14 are repeatedly executed.

  Thereafter, when an external force is applied to the conductive spring 43 and the conductive spring 43 is elastically deformed to contact the peripheral edge of the barbed insertion hole 41a of the conductive plate 41, the sensor 1 switches from off to on. The determination result in S13 is inverted to “YES”. For this reason, it is determined whether or not the switching from the OFF state to the ON state of the sensor 1 is the first time (S15). Since this time is the first time, the determination result in S15 is “YES”, and then the elapsed time Measurement of time 1 is started (S16). Here, the elapsed time 1 is an elapsed time from the time point (first time point t1) when the sensor 1 performs the first switching from OFF to ON. Next, the number of sensor inputs, that is, the number of times the sensor 1 is switched from OFF to ON is counted (S17), and the process 1 is exited.

  In the next process 1, since the sensor 1 is already in the on state, the determination result in S13 is reversed to “NO”, and then it is determined whether or not the sensor 1 is in the on state (S14). Since the determination result is “YES”, it is next determined whether or not the sensor 1 is switched from on to off (S18). At this time, since the sensor 1 is in the ON state, the determination result in S18 is “NO”, and then it is determined whether the elapsed time 1 is equal to or shorter than a first predetermined time (for example, 2 seconds) (S19). Here, the first predetermined time is limited to the time during which the sensor 1 has been switched on from the time of the first switching from off to on (first time t1), and the first predetermined time is within the first predetermined time. When the sensor 1 is not switched from ON to OFF and the ON state continues, the time is set so that the leaf portion of the carnivorous plant model 2 is not closed. At this time, since the sensor 1 is immediately after being turned on, the determination result in S19 is “YES”, and the process 1 is exited.

  If the external force applied to the conductive spring 43 is released and the sensor 1 is switched from on to off before the first predetermined time elapses from the first time point t1, the determination result in S18 is reversed to “YES”, and then Then, the measurement of elapsed time 2 is started (S20), and the process 1 is exited. Here, the elapsed time 2 is an elapsed time from the time (second time point t2) when the sensor 1 switches from the first on to the off. Thereafter, S11, S12, S13, and S14 are repeatedly executed until the sensor 1 performs the second switching from OFF to ON.

  After that, when an external force is applied again to the conductive spring 43 and the sensor 1 performs the second switching from OFF to ON at the third time point t3, the determination result of S13 is reversed to “YES”, and then the sensor 1 It is determined whether or not switching from OFF to ON is the first time (S15). At this time, since it is the second time, the determination result in S15 is “NO”, and then the elapsed time 2 is the second time. It is determined whether or not a predetermined time (for example, 3 seconds) or less (S18). Here, the second predetermined time is limited to a time during which the sensor 1 is switched from on to off (second time t2) and has been kept off, and the sensor 1 is turned off within the second predetermined time. This is a time period for preventing the leaf portion of the carnivorous plant model 2 from being closed when the OFF state continues without switching from ON to ON.

  When the elapsed time 2 until the time point when the sensor 1 switches from OFF to ON for the second time (third time point t3) is equal to or shorter than the second predetermined time, the determination result in S21 is “YES”, and then the heat Energization of the shrinkable metal wire 40 is started (S22), energization time measurement is started (S23), waiting time measurement is started (S24), and elapsed time 1 and elapsed time 2 are cleared (S25). ), The light emitting diode 34 is turned on (S26). When energization to the heat-shrinkable metal wire 40 is started, the heat-shrinkable metal wire 40 generates heat by energization and comes to heat shrink. When the heat-shrinkable metal wire 40 is thermally shrunk, the loop portion 39 of the linear member 38 receives a downward biasing force, and a pair of plate portions 52 resists the biasing force of the return coil spring 53 of the hinge 35. Approach each other and the leaf 30 closes. Further, the light emitting diode 34 is turned on.

  In the next process 1, since the heat-shrinkable metal wire 40 is energized, the determination result of S11 is reversed to “YES”, and whether or not the energization time is equal to or shorter than a third predetermined time (for example, 3 seconds). S11 and S27 are repeatedly executed until the energization time reaches the third predetermined time. Here, the energization current value to the heat-shrinkable metal wire 40 may be constant, but the shrinkage operation of the heat-shrinkable metal wire 40 is ensured even if it is decreased stepwise or continuously over time. In this case, the power consumption of the battery 301 can be suppressed.

  Thereafter, at the fourth time point t4 when the energization time from the third time point t3 reaches the third predetermined time, the determination result of S27 is reversed to “NO”, and then the power supply to the heat-shrinkable metal wire 40 is stopped. Then, the energization time is cleared (S29). After energization of the heat-shrinkable metal wire 40 is stopped, the heat-shrinkable metal wire 40 does not generate heat and extends to the original state. Therefore, the downward biasing force acting on the loop portion 39 of the linear member 38 disappears, and the pair of plate portions 52 are separated from each other by the biasing force of the return coil spring 53, so that the leaf portion 30 opens. Become.

  In the next process 1, since the power supply to the heat-shrinkable metal wire 40 is stopped, the determination result of S11 is reversed to “NO”, and then it is determined whether or not the waiting time is being measured ( S12). At this time, since the waiting time is measured, the determination result in S12 is “YES”, and then it is determined whether or not the waiting time is equal to or shorter than a fourth predetermined time (for example, 12 seconds) (S30). ), S11, S12, and S30 are repeatedly executed until the waiting time reaches the fourth predetermined time. Here, the 4th predetermined time respond | corresponds to the time required after the energization to the heat-shrinkable metal wire 40 is stopped until the heat-shrinkable metal wire 40 is completely extended to the original state. . Until the waiting time reaches the fourth predetermined time, S11, S12, and S30 are repeatedly executed as described above, so that the sensor 1 is turned off until the waiting time reaches the fourth predetermined time. Even if it switches from ON to ON, electricity supply to the heat-shrinkable metal wire 40 is not performed at all.

  Thereafter, when the waiting time reaches the fourth predetermined time, the determination result of S30 is reversed to “NO”, the waiting time is cleared (S31), the sensor input count is cleared (S32), and the light emitting diode 34 is turned off. (S33).

  Accordingly, as shown in the timing chart of FIG. 8, the sensor 1 switches from on to off before the first predetermined time (2 seconds) has elapsed from the first time point t1 when the sensor 1 switches from off to on, and When the sensor 1 is switched from off to on again at the third time t3 before the second predetermined time (3 seconds) elapses from the second time t2 when the sensor 1 is switched from on to off, the heat-shrinkable metal Energization of the wire 40 is performed for a third predetermined time (3 seconds) from the third time point t3, and the energization of the heat-shrinkable metal wire 40 is stopped at a fourth time point t4 when the third predetermined time has elapsed. And until the 4th predetermined time passes from the 3rd time t3, even if the sensor 1 switches from OFF to ON, the electricity supply control to the heat-shrinkable metal wire 40 is not performed at all.

  On the other hand, as shown in FIG. 9, when the sensor 1 has been on for more than the first predetermined time from the first time point t1 when the sensor 1 switched from off to on for the first time, S19 The determination result is reversed to “NO”, the elapsed time 1 and the elapsed time 2 are cleared (S34), the count of the sensor input is cleared (S35), and the heat-shrinkable metal wire 40 is not energized at all. . Further, as shown in FIG. 9, the second time from when the sensor 1 switches from on to off at the third time t3 after the second predetermined time has elapsed from the second time t2 when the sensor 1 switches from on to off. When the switching is performed, the determination result in S21 is inverted to “NO”, the elapsed time 1 and the elapsed time 2 are cleared (S34), the sensor input count is cleared (S35), and the heat-shrinkable metal wire 40 is reached. Is not energized at all.

  In the carnivorous plant potted model configured as described above, when the user turns on the explanation button 203, the explanation about the carnivorous plant potted model and the healing words recorded in advance on the voice board 200 are spoken. Is output from the speaker 201.

  As described above, the carnivorous plant model 2 of the present embodiment is the stem portion 20 and the leaf portion 30 arranged at the tip of the stem portion 20, and is arranged with the pivot portion 32 and the pivot portion 32 interposed therebetween. A leaf portion 30 having a substantially V-shaped cross section having a pair of leaf pieces 33 and a hinge 35 disposed inside the leaf portion 30 in accordance with the outer shape of the leaf portion 30, and the pivot portion of the leaf portion 30 32, and a pair of plate portions 52 that are connected to the fixed shaft portion 51 and located inside the pair of leaf pieces 33, and are rotated by using the fixed shaft portion 51 as a rotation axis. A hinge 35 having a pair of plate portions 52 that change in angle with each other, and a linear member 38 that is connected to the pair of plate portions 52 and passes through the inside of the stem portion 20. Operation to apply a biasing force in the closing direction to the plate portion 52 is controlled. And a linear member 38.

  According to the carnivorous plant model 2 of the present embodiment, the hinge 35 is arranged inside the leaf portion 30 and the linear member 38 is inserted into the stem portion 20, so that the hinge 35 and the linear member 38 are outside. It is not exposed and the appearance of the carnivorous plant model 2 is not impaired. Further, by controlling the operation of the linear member 38, the pair of plate portions 52 can be urged in the closing direction and the leaf portion 30 can be closed, which is similar to the movement of a carnivorous plant when capturing a fly. It is possible to express the movement.

  In addition, the carnivorous plant model 2 of the present embodiment is a conductive plate (conductive member) 41 located inside each of the pair of leaf pieces 33, the conductive plate 41 having a barb insertion hole 41a, An elastically deformable conductive spring (barbed member) 43 provided so as to pass through the spine insertion hole 41a so as not to contact the conductive plate 41 and to protrude from the surfaces of the pair of leaf pieces 33 facing each other. And a conductive spring 43 made of a conductive elastic member that can come into contact with the conductive plate 41 when elastically deformed. The control circuit 100 is in contact with the conductive plate 41 as the conductive spring 43 is elastically deformed by an external load. When this is detected, the operation of the linear member 38 is controlled so as to apply a biasing force in the closing direction to the pair of plate portions 52. As described above, since the conductive spring 43 and the conductive plate 41 are brought into contact with each other by using the elastic deformation of the conductive spring 43, the state in which the fly is stopped at the fly's thorn is changed to the elastic deformation of the conductive spring 43. In addition, it is possible to detect electrically by the contact between the conductive spring 43 and the conductive plate 41, and it is possible to make the operation closer to the actual operation of the jumper with a simple structure.

  The linear member 38 includes a loop portion 39 and a line portion 40 extending from the loop portion 39. The loop portion 39 includes a line insertion hole 52b formed in each of the pair of plate portions 52 and each plate. A loop passing through the end portion 52 a near the stem portion 20 in the portion 52 is drawn, and the line portion 40 is connected to the lower end portion 39 c of the loop portion 39. The linear member 38 has a loop portion 39, and the loop portion 39 causes a force in a direction in which the pair of plate portions 52 are brought close to each other to the end portions 52 a near the stem portion 20 of the pair of plate portions 52. Therefore, even if the force applied to the loop portion 39 is relatively small, a relatively large force can be applied to the pair of plate portions 52.

  Further, the end portion 40b of the wire portion 40 that is not located on the loop portion 39 side is fixed, and at least a part (all in the present embodiment) of the wire portion 40 is contracted by energization. The heat-shrinkable metal wire (variable length portion) 40 is configured to apply a biasing force in the closing direction to the pair of plate portions 52 by the loop portion 39 based on the shrinkage of the heat-shrinkable metal wire 40. . By using the heat-shrinkable metal wire 40, the mechanism for opening and closing the leaf portion 30 can be greatly simplified.

  Further, when the control circuit 100 detects that the conductive spring 43 is elastically deformed by an external load and has come into contact with the conductive plate 41, the control circuit 100 energizes the heat-shrinkable metal wire 40 and heat-shrinkable metal wire 40. Shrink. The state in which the fly stops at the spine of the fly rush is electrically detected by the contact between the conductive spring 43 and the conductive plate 41 which are elastically deformed, and the heat-shrinkable metal wire 40 is contracted to thereby make the loop portion 39 and the hinge. Since the leaf portion 30 can be closed via 35, it is possible to reproduce the actual action of the fly fly that closes when the fly stops at the spine of the fly fly.

  The heat-shrinkable metal wire 40 is energized with the conductive spring 43 and the conductive plate 43 before the first predetermined time elapses from the first time point t1 when the conductive spring 43 and the conductive plate 41 contact the first time. The contact state with the conductive plate 41 is released, and the conductive spring 43 and the conductive plate 41 make the second contact before the second predetermined time elapses from the second time point t2. And start at the third time point t3 when the conductive spring 43 and the conductive plate 41 make the second contact. By controlling the power supply to the heat-shrinkable metal wire 40 in this way, the actual operation of the fly rush, that is, if the fly first stops at the spine, the leaf does not close, but in a relatively short time. The action of closing the leaf when the fly stops on the spine twice can be reproduced.

  The energization of the heat-shrinkable metal wire 40 is stopped at the fourth time point t4 when the third predetermined time has elapsed from the third time point t3. When the energization of the heat-shrinkable metal wire 40 is stopped, the heat-shrinkable metal wire 40 is cooled and can return to the original state, that is, the expanded state, and therefore the leaf portion via the loop portion 39 and the hinge 35. 30 can be opened, and the action of actual fly fly leaves opening can be reproduced.

  Further, in the energization of the heat-shrinkable metal wire 40, the current value decreases between the third time point t3 and the fourth time point t4. When the energization current value to the heat-shrinkable metal wire 40 is decreased stepwise or continuously as time elapses, the power consumption of the battery 301 is suppressed while ensuring the shrinkage operation of the heat-shrinkable metal wire 40. It becomes possible.

  Further, the energization of the heat-shrinkable metal wire 40 is not performed until the fourth predetermined time elapses from the third time point t3 when the energization of the heat-shrinkable metal wire 40 is started. By providing such a waiting time, the leaf portion 30 can be completely opened.

  Further, the control circuit 100 outputs a predetermined sound (explanation of the carnivorous plant potted model or the like) from the sound generation device (the sound board 200, the speaker 201) to the outside at a predetermined timing (when the explanation button 203 is turned on). Healing words). With this voice, the user can know the mechanism and operation method of the carnivorous plant potted model, and healed by healing words.

  Further, the light emitting diode 34 is disposed in the leaf portion 30, and the control circuit 100 causes the light emitting diode 34 to emit light at a predetermined timing (when energization to the heat-shrinkable metal wire 40 is started). When the light emitting diode 34 emits light, the degree of attention to the leaf portion 30 can be increased.

  Moreover, since the carnivorous plant model 2 of the said structure is arrange | positioned in the pot body 1 so that it may extend upwards from the stem insertion hole 4a of the cover body 4 attached to the pot body 1, when carnivorous plants are planted in a pot It is possible to provide a carnivorous plant potted model that mimics the form of the above.

  In the above-described embodiment, the lower end portion 22a of the pipe core member 22 is in a substantially vertical state, but the entire pipe core member 22 is inclined in a direction approaching the horizontal, and the lower end portion 22a is set in an inclined state. In this case, it is desirable that the line portion 40 extending downward from the loop portion 39 of the linear member 38 is also preferably set in an inclined state in accordance with the inclination of the lower end portion 22a. (Heat-shrinkable metal wire) The load that the linear member 38 receives due to friction with the inner peripheral surface of the pipe core 22 when the 40 contracts can be reduced. In the above embodiment, the expansion plate 36 is described as a member separate from the hinge 35, but the expansion plate 36 may be regarded as a part of the hinge 35.
